Dust extraction woodwork

Is it practical to build a 50mm cyclone between two 100mm diameter suction hoses or does that cause more problems than it helps in terms of flow?

I would expect that to look like an obstruction in the path. Might reduce flow too much. I could do some calculations when I get home to see what the impact would be.
